Acta Zoologica Academiae Scientiarum Hungaricae 49 (1), pp. 71–85, 2003 NEW ORIENTAL SPECIES AND RECORDS OF SPHAEROCERINAE AND COPROMYZINAE (DIPTERA: SPHAEROCERIDAE) L. PAPP Department of Zoology, Hungarian Natural History Museum H-1088 Budapest, Baross utca 13, Hungary, E-mail: [email protected] Two new species ofthe genus Ischiolepta – I. baloghi sp. n. from India and I. peregovitsi sp. n. from Nepal; one new species each of Crumomyia (C. topali sp. n. from India) and Norrbomia (N. nepalensis sp. n. from Nepal); and a new subspecies of Metaborborus flavior (VAN- SCHUYTBROECK), M. f. orientalis ssp. n. from Nepal, are described. Several other species of the two subfamilies are reported from the Oriental region (Nepal, India, Thailand and Tai- wan). With 28 original figures. Key words: Sphaeroceridae, Sphaerocerinae, Copromyzinae, new species, taxonomy, Orien- tal Region INTRODUCTION The Oriental species ofSphaeroceridae are rather little known (H ACKMAN 1977), although some significant contributions were published in the last two de- cades. Several genera, which formerly were thought to be Afrotropical, were reported from Oriental areas: e.g. Lotobia LIOY (HAYASHI 1994), Metaborborus VANSCHUYTBROECK (NORRBOM &KIM 1985b), Achaetothorax HEDICKE (PAPP & NORRBOM 1992). Last year, extra-Palaearctic specimens ofSphaeroceridae in the collection of the Hungarian Natural History Museum were studied. Some ofthe results relating to species in the subfamilies Sphaerocerinae and Copromyzinae are presented below. Both subfamilies are new to Taiwan (cf. LIN & CHEN 1999). Terminology ofmale genitalia followsS INCLAIR (2000) whenever possible. My annotations oflabel data and those ofthe preservation ofthe specimens are given in square brackets below. The specimens are in the Diptera Collection ofthe Department ofZoology, Hungar - ian Natural History Museum, Budapest (HNHM). SPHAEROCERINAE Sphaerocera curvipes LATREILLE, 1805 – 4 males: Nepal, Royal Chitwan National Park, Bandarjhola Island – Jungle Island Resort, 84°10’E, 27°35’N, 150 m, 1995.10.30. – swept on Acta zool. hung. 49, 2003 Hungarian Natural History Museum, Budapest 72 L. PAPP Elephas maximus dung, leg. L. Peregovits (17 specimens captured but only these four were pinned). This species is by now almost cosmopolitan, spread by the human activity, although this is its first re- cord from Nepal (known from Kashmir in the Oriental region: ROHÁČEK et al. 2001). Sphaerocera pseudomonilis asiatica L. PAPP, 1988(a)–1female: India, Calcutta, West Ben- gal – No. 436, 30.V.1980, leg. Topál. New to India. The subspecies of S. pseudomonilis (ROHÁČEK et al. 2001) need revision, as they may well be true species. Ischiolepta baloghi sp. n. (Figs 1–4) Holotype male (HNHM): India, Goomti, Darjeeling Distr. – No. 113, 20. II. 1980, leg. Topál [abdomen with genitalia in a plastic microvial with glycerol]. Measurements in mm: body length 2.00, wing length 2.17, wing width 0.74 . Body dark, blackish brown, grey microtomentose. Head as long as high, lunule short but broad, inner vertical seta pale short, on a minute tubercle, outer vertical seta short, thick, proclinate, on larger tubercle. Three pairs oforbital tubercles with short setae just above eye: anterior one reclinate, middle one lateroclinate, posterior one proclinate. Epistoma (facial plate) pentagonal, upper triangle much higher than broad, basal part. Clypeus dark, about twice as broad as high, dull grey microtomentose. Supragena and infragena subshiny, rubbed shiny on the left side on holotype. Facial ridge with thick but only slightly flattened vibrissa 0.106 mm long, only short pale setae ventral to vibrissa. Eye round, globular. Thorax rather short. Acrostichal setae anteriorly in 4 irregular rows, posteriorly in ca. 6 rows, dorsocentral rows distinctly though very narrowly separate from acrostichal rows, bare area between them microtomentose. Scutellum more than twice as broad as long with 8 scutellar marginal tubercles. Katepisternum with very sparse hairs ventrally (unfortunately in glue on the holotype). Legs as dark brown as thoracic pleura. Fore coxa yellowish brown laterally, mid and hind coxae and bases of mid and hind femora yellowish. Male femora not much thickened, fore femur 0.138 mm thick, hind femur without a tubercle, 0.112 mm thick at thickest, i.e fore femur 1.23 times as thick as hind femur, hind femur and tibia almost straight, not bent dorsally. Ventral spur on apex of hind tibia thick black but only halfas long as diameter oftibia subapically. Wings not hyaline but light brownish, veins light brown. Knob ofhalteres ochre. Preabdomen strongly sclerotized dark brown. Male tergite 1+2 large, almost twice as long as T3, T4 slightly longer than T3, tergite 5 symmetrical, ca. 4 times as broad as long, and less than 1/2 of length ofT4, medially without the slightest sign ofweakening. All sternites shorter than broad with a pair ofblunt marginal setae, sternite 4 halfas long as broad, sternite 5 slightly asymmetrical and as long and halfas broad as tergite 5. Male terminalia (Figs 1–4) and postabdomen comparatively short but broad. Hypandrium normal. Periandrium (ofR OHÁČEK &PAPP 1984, in all probability ventral/posterior part ofepandrium, cf. ROHÁČEK 1998: 465) in two lateral parts (Fig. 1), trapezoidal with 1 long seta, partly fused with cerci (pseudocerci ofR OHÁČEK &PAPP 1984). Cerci basally broad, projecting downward to about middle ofsurstyli, apically much narrowed but not pointed, subapically with a pair oflong but not thick setae, otherwise with a number ofmedium-long setae. Surstylus (Fig. 2) without frommedially to anterally torn part on caudal edge as in I. pusilla. Surstylus in broadest extension broadly rounded apically but not narrow even basally, slightly asymmetrical (at least on the holotype, Fig. 1), lateral surface with several long and medium-long setae, medial surface with even more medium-long setae. Acta zool. hung. 49, 2003 NEW SPECIES AND RECORDS OF SPHAEROCERINAE AND COPROMYZINAE (DIPTERA) 73 Postgonite (Fig. 4) very characteristic with its long, curved, but apically blunt apical process, and comparatively slender, almost unarmed basal process. Apical process with two short subapical and one longer submedial setae. Distiphallus (Fig. 3) in contrast to I. pusilla, with no apical tubuliform processes, its sclerotized pair ofprocesses comparatively thin and very asymmetrical. Female unknown. Ischiolepta baloghi sp. n. runs to the species group of I. pusilla in the key of HAN and KIM (1990): thoracic dorsum normal, body not as small as in scabricula or minuscula, outer vertical seta small and sitting on a small tubercle, mesonotal setae originate on very weak tubercles, epistoma and clypeus dark, genal area not distinctly granulated, mesonotum microtomentose, male hind femur without a small ventral tubercle, and acrostichals in 4 or more irregular rows. Its male genitalia are characteristic with a broad surstylus, a distiphallus (Fig. 3) with no apical tubuliform processes, and a pair of comparatively thin, very asymmetrical scler- otised processes, only one ofwhich is hooked upwards. Its postgonite is markedly different from that of both I. pusilla and I. vaporariorum. Etymology. This species is dedicated to the honour ofthe late ProfessorJ ÁNOS BALOGH, mas- ter ofgenerations in Hungarian zoology, incl. both the collector and the author ofthis new species. Figs 1–4. Ischiolepta baloghi sp. n., holotype male, genitalia: 1 = terminalia caudally with caudal end ofright hypandrial arm, 2 = surstylus, broadest extension, 3 = distiphallus, lateral view, 4 = post - gonite, widest (nearly lateral) view.

Body dark brown with rather weak shine, legs ochre or light brownish yellow. Head as long as high; lunule comparatively small, inner vertical setae indistinct, outer vertical setae short, thick, on small tubercles, 2 pairs ofcomparatively short proclinate upper orbital (fronto- orbital) setae on weak tubercles. Epistoma (facial plate) pentagonal, granulated, upper triangle only as high as broad basal part. Clypeus more than twice as broad as high. Epistoma and clypeus light brown, i.e. contrasting gena, etc. Supragena, infragena and facial ridge subshiny, definitely granulated; facial ridge with thick but only slightly flattened vibrissa (0.07 mm long on holotype), sub- vibrissal hairs minute. Eye subspherical. Thorax not long, mesonotal setae sparse and rather strong. Acrostichal setae in 2 rather well-ordered rows on anterior halfofmesonotum, in 4 irregular rows prescutellarly; dorsocentral rows distinctly separate from acrostichal rows, bare area between them dark microtomentose. Scutellum twice as wide as long with 8 scutellar marginal tubercles, medial tubercles somewhat re- duced, smaller than lateral 3 pairs. Katepisternum with very sparse hairs ventrally. Legs light, brownish yellow or ochre. Male fore femur very thick, 0.603 mm long and 0.195 mm thick, mid femur 0.117 mm thick, hind femur 0.258 mm thick, i.e. 2.21 times as thick as mid femur and 1.32 times as thick as fore femur; both hind femur and tibia bent dorsally. Hind tibia with a normal ventroapical spur, which is comparatively short and not thick, only halfas long as tibial diam - eter subapically, i.e. shorter and thinner than in I. orientalis or in I. draskovitsae. Also this new species possesses a short sharp perpendicular spur posteriorly on the tibial apex.
